When Google was just a mighty search engine, the company championed an open, unfettered Internet. Now that it’s selling ultra-fast broadband Internet and TV service in Kansas City, Mo., with plans to repeat the service elsewhere, the tech giant bars customers from hosting servers on the Google Fiber network without written permission.

In some tech circles, that’s seen as at least a partial reversal by Google, one that might undercut the company’s position in coming regulatory battles over the concept known as net neutrality.

In the past, Google has been an outspoken advocate for net neutrality, a set of regulations that prevent Internet service providers from giving a preference to any type of Internet traffic over another or blocking any lawful content, applications, services or devices.
